Why use phenolpthalein indicator?

Well (i) because it is convenient and (ii) it works like a charm I usually find phenolphthalein to be the indicator of choice in acid-base titrations (i e the base is the titrant) The COLOURED form is the basic form and in an acid milieu it is COLOURLESS And the endpoint is VERY easy to recognize given that it goes from colourless to light pink In a titration we titrate to the

Enantioselective Addition of Boronates to Chromene

The optimal carboxylic acid is the easily available tartaric acid amide shown in the scheme Spectroscopic and kinetic mechanistic studies demonstrate that an exchange process generates a reactive dioxoborolane intermediate leading to enantioselective addition to the pyrylium ion formed from the chromene acetal

How to Extract the Citric Acid From Lemons

Citric acid is an organic acid that is most often found in citrus fruits It has a very high concentration in lemons -- there can be as much as 8 percent of citric acid in the dry weight of a single lemon The acid has a distinctive sour taste and because of this it is added to some foods and drinks To extract the citric acid from a lemon you'll need to add a strong acid such as sulphuric
